Application of spiral steel pipe

Application of spiral steel pipe Spiral steel pipes are mainly used in water supply projects, the petrochemical industry, the chemical industry, the electric power industry, agricultural irrigation, and urban construction. They are one of the twenty key products developed in my country. For liquid transportation: water supply and drainage. For gas transportation: coal gas, steam, liquefied petroleum gas. For structural purposes: piling pipes, bridges; pipes for docks, roads, building structures, etc. Spiral steel pipe is a spiral seam steel pipe welded by automatic double-wire double-sided submerged arc welding process using strip steel coil plate as raw material, constant temperature extrusion molding. The spiral steel pipe feeds the strip into the welded pipe unit. After being rolled by multiple rollers, the strip is gradually rolled up to form a circular tube blank with an opening gap. Adjust the reduction amount of the extrusion roller to control the weld gap between 1~ 3mm, and make both ends of the welding joint flush. Biaxial caliper with adjustable measuring range. This equipment can continuously roll seamless steel, Pilger rolling seamless steel, straight seam welded pipe, spiral welded pipe, etc. It can be directly installed in the production line for online measurement, and can also be installed in the flaw detection line, The inspection line measures the outer diameter of the finished pipe. The equipment has two sets of double-side heads with an adjustable measuring range. The measuring range is automatically adjusted by a servo motor. After the adjustment is completed, the measurement accuracy can be guaranteed without calibration. The equipment can be equipped with an external circulation cooling system, a duckbill side-blowing dust-proof system, an embedded intelligent module, a host computer control system, an external LED display, etc. At the same time, the data can be transmitted to a network database and the data can be viewed in real-time through a mobile phone or computer. According to needs, the lower part of the equipment can be equipped with an automatic height-adjusting lifting platform to automatically adjust the height of the measurement center.
